This is an introduction to tau as a performance tool.
The following guide describes how to execute ATELES with tau to get a performance analyses. Before executing ATELES with tau read the following instructions carefully. 

The following steps have to be done before executing ATELES:

Step 1: 
  module switch openmpi intelmpi
  export CC=icc
  export FC=mpiifort 

Go to the ATELES directory, 
  cd /your_folders/ateles

load the tau module:
  module load UNITE tau/2.20.3-intel2-intel-papi

Compile ATELES with tau options by:
  ./waf tau

Step 2: 
Execute ATELES under observation of tau and its performance tools. The following file is an example file for the Cluster-beta system of of RWTH Rechenzentrum which executes ATELES there:
test/performance/tau/tau_ateles.lsf
Before submitting this job to the queue of the Cluster-beta system please check if the directory given in this file are the correct ones on your account.
The job is then submitted to the queue of the system by:
  bsub < test/performance/tau/tau_ateles.lsf

Step 3:
Now, analyse the files written by tau. This can be done using paraprof:
